Be itknown that I, EDWARD VVALDnRpcitizenjof the United, States'k and resident of fr Kansas City; county of Wyandotte State ollMissourLlhave invented a certain new `and useful'lrnproveinent in Electric Heaters, of

which thefollowfing is a complete specification. 1

.This inventionrelatesl to electricheaters offthat general. class comprising a ceinent .vbo'dyrin which provision` is made' for air to enter:` at the bottom and Vesjcapef'at the top,- resisftance'coils located within the body in the pathof such air tofheatv the'saine as it passes upwardly,`y and my object is to produce a i heater Ofxthis character which will 'operate -`etliciently,r'which #is susceptible. of being knocked down :for` convenience of portabilf y ity; andfwhri'ch isv of si1nple,fstrong,` durable i 1 ,'W'th'this' objectrin view, the invention f and inexpensive construction.

ing 6 and Vforming in conjunction therewith a circular or cylindrical opening wherein is litted a socket 10 for engagement by a ycord `-'I 'o secure thecircular kblocks 4 and 7 rigidlytogetherandyet provide for their separation when necessary, bolts 11 extend through one of the'bracketsv `2 kand up through said blocks and are engaged at their iipperends by washers'12 and clamping nuts 18, the latter serving to clamp the washers firmly down upon the'block Arranged vertically withinV theV passage .formed bythe registering openings 5y and 8 is a pairo tubes 14 ofwporcelain or the like,` susceptible of being highly heated withe out fracturiiig, and said tubes at their lower ends are enlarged to form upwardlyy lfacing v shoulders 15.v The tubes respectively rest upon U-shaped retainers 16 of wire, the con? nection being'madc secure by overlapping the upper ends ofthe legs of said retainers Von the sai d shoulders 15. rllhe retainers rest upon the brackets 2 and at their centers are 1 formed with eyes 17 through which headed screws 18 extend, lsaidsc'rews also extending through said bracket 2 and being secured in position by clan'iping nuts 19 engaging their .threaded ends.

'Secured upon the tubes vv141e respectively the lower terminals of said coils Vwhich are resistance coils, being connected as at 22 to thejsocket 10 in the usual or any preferred mannen the upperends of the vcoils being' wardly and outwardly 'for the purpose of directing the hot air downwardly toward the floor of the rooin` in which the heater is located. The cylinderr is provided with a cover 6 of concrete or thelike, the said cover dependingslightly within the body to guard against accidental dislodgment.

A. heater of this character is adapted to are clamping bands'207 forming rests for ,y coiled wires 21 inclosing said'tubes respectively for they greater part of their length,

v orniing a continuation of the opening 5 ot iio be connected by a cord and plug (not shown) with a wall socket or the like, and within a very short time the resistance coils raise the insulating tubes to a high temperature, the 'high temperature developed resulting in a circulation of air up through the passage composed of openings 5 and S and the interior of the tubes 14, this air escaping downwardly and outwardly through the exit openings 25.

A heater of the type described is not only efficient in operation, but it minimizes danger of lire and is of such weight that it cannot readily be knocked over, the making of it in sections permitting it to be handled readily by a single attendant so that it can be set up at any desired point with ease and convenience.

From the above description, it will be apparent that I have produced an electric heater embodying the features of advantage set forth as desirable in the statement of the object of the invention, and which may be modified in minor particulars without departing from the spirit and scope of the appended claims.

I claim:

l. A heater comprising a skeleton base, a cement block resting upon the base and provided with an opening, a second cement. block superimposed upon the first and provided with a registering opening, a plurality of tubes extending vertically through the passage formed by said registerinor openings, means for fastening said tubes to the said base, resistance coils encircling said tubes and connected together to transmit electric current from one of the coils to the other, a hollow cylindrical body inclosing said block and resting on said base and provided in a plane above that of the block with exit openings, and a cover closing the upper end of said body.

2. An electric heater comprising a skelel ton base, a concrete or cement block resting on the base and provided with a vertical opening, a second concrete block resting upon the first and provided with a vertical opening registering with the opening of said first block, a plurality of tubes extending said opening and provided at their lower ends with upwardly facing shoulders, U-

shaped retainers interposed between said tubes and said base and interloeked with said shoulders to prevent upward movement of said tubes, beams fastening said retainers to said base, resistance coils inclosing said tubes and connected together in series, a hollow body fitting over said block and resting on said base and provided at its upper end with exit openings, and a cover for said body.

3. A heater comprising a skeleton base, a cement block resting upon the base and provided with an opening, a second cement block superimposed upon the first and pro vided with a registering opening, a plurality of tubes extending vertically through the passage formed by said registering openings, means for fastening said tubes to the said base, resistance coils encircling said tubes and connected together to transmit electric current from one of the coils to the other, a hollow cylindrical body inclosing said block and resting on said base and provided in a plane above that of the block with exit openings, and a cover closing the upper end of said body and fastening devices extending up through said base and said superposed block.

e. A heater comprising a skeleton base, a cement block resting upon the base and provided with an opening, a second cement block superposed upon the first and provided with a registering opening, a plurality of tubes extending vertically through the passage formed by said. registering openings, means for fastening said tubes to the said base, resistance coils encircling said tubes and connected together to transmit electric current from one of the coils to the other, a. hollow cylindrical body inclosing said block and resting on said base and provided in a plane above that of the block vith exit o eninffs and a cover closin0r thel upper end of said body; the juxtaposed faces of said blocks having grooves conjointly forming openings extending from the periphery of said blocks to the openings thereof, and an electric socket connected to the lower end of said coil.

In testimony whereof, I hereto aflix my signature.
